[PATCH -next] modpost: move some defines to the file head

[Kefeng Wang <wangkefeng.wang@huawei.com>]

with "module: Ignore RISC-V mapping symbols too", build error occurs,

scripts/mod/modpost.c: In function ‘is_valid_name’:
scripts/mod/modpost.c:1055:57: error: ‘EM_RISCV’ undeclared (first use in this function)
  return !is_mapping_symbol(name, elf->hdr->e_machine == EM_RISCV);

Fix it by moving the EM_RISCV to the file head, also some other
defines in case of similar problem in the future.
